How to reset the NVRAM or PRAM on an any Mac, including M1's and M2's

If you’ have a an M1 Mac, resetting the NVRAM or PRAM is as simple as restarting your computer as it happens automatically every time you restart.

Just shut down your M1 MacBook Pro, Macbook or Mac Mini , wait a few seconds, and then press the power button then turn it back on. 


For older Macs like the Mac Pro 2013 Black Desktop or older non M1 Macbook and Macbook Pro Here is how to Reset the PRAM.​​​​​​​

  1. Shut down your computer and disconnect all USB devices (except wired keyboards).
  2. Press the power button to turn on your Mac.
  3. Quickly press and hold the Option, Command, P, and R keys on your keyboard. You need to press this key combination before the gray screen appears or it won’t work.

    I know its hard to press all 4 at once so here is a tip put your fingers on the keyboard to see the best way you can hit all 4 keys at the same time. I use my Left hand Pointer finger for option Thumb for command, I use my right hand and select with my  Pinky the P and use my thumb for the R.

  1. Hold down all 4 keys for 10-20 seconds, then the Mac will restart.

    On older Macs that chime on startup, hold down the keys until you hear a second chime.

    For Macs with the Apple T2 Security Chip, hold the keys until the Apple logo appears and disappears a second time.
    Here’s a list of Mac models with the T2 chip.
  2. Release the keys and let your Mac finish rebooting.

Be aware after your perfiorm the reset some of your user settings will get reset, here are a few, keyboard layout, mouse tracking, startup disk, date and time, and volume.

Once you restart check your System Preferences and adjust anything that was changed and thats all there is to it.
